==Persiapan==


Step 1Install gnu-radio
Buat directory

It looks like there are two options for installing an up-to-date gnuradio on ubuntu:


1) use an install script
mkdir /usr/local/src/SDR
2) install from source
cd /usr/local/src/SDR


Don't ask me why, but I tried the second option (probably the harder). After a first attempt that failed, I went for the first (and recommended option) to much success! So... lesson learned. Note to self, follow advice of program developers when installing software.

My advice, use the install script.  
sudo apt-get install cmake swig libcppunit-dev python-cheetah doxygen \
libboost-all-dev python-sphinx fftw3-dev python-numpy libqwt-dev \
libusb++-dev libusb-dev libusb-1.0-0-dev libgsl0-dev python-wxgtk2.6 git \
autoconf automake qtcreator


==Install GNURadio==


Lakukan


cd /usr/local/src/SDR
git clone git://gnuradio.org/gnuradio


Compile


Step 2Install rtl-sdr tools
cd /usr/local/src/SDR/gnuradio
Next, you want to install any missing rtl-sdr specific tools from here:
mkdir build
 
cd build
  http://sdr.osmocom.org/trac/wiki/rtl-sdr
  cmake ../
make
sudo make install
sudo ldconfig


Again, rather than duplicating instructions, follow the steps outlined here to install the rtlsdr library & capture tool: git://git.osmocom.org/rtl-sdr.git
==Install rtl-sdr tools==


Although this page also mentions a gnu radio module (git://git.osmocom.org/gr-osmosdr) I was unable to get it to work. Instead, I installed:
Lakukan


  https://github.com/balint256/gr-baz
  cd /usr/local/src/SDR
git clone git://git.osmocom.org/rtl-sdr.git


as recommended from here: http://2h2o.tumblr.com/
Masuk ke directory rtl-sdr & lakukan


the basic steps are:
cd /usr/local/src/SDR/rtl-sdr/
mkdir build
cd build
cmake ../


git clone https://github.com/balint256/gr-baz
cd gr-baz
sh bootstrap
./configure
  make
  make
  sudo make install
  sudo make install
  sudo ldconfig
  sudo ldconfig


Now you should have all the necessary software to communicate with the DVB-T dongle using gnuradio.

Step 3Setup udev rules
Next, you need to add some udev rules to make the dongle available for the non-root users. First you want to find the vendor id and product id for your dongle.
 
The way I did this was to run:


  lsusb
  lsusb


The last line was the Realtek dongle:
Keluar


  Bus 001 Device 008: ID 0bda:2838 Realtek Semiconductor Corp.
  Bus 001 Device 003: ID 0bda:2838 Realtek Semiconductor Corp.


The important parts are "0bda" (the vendor id) and "2838" (the product id).

Create a new file as root named /etc/udev/rules.d/20.rtlsdr.rules that contains the following line:
==Install gr-baz==


SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="2838", GROUP="adm", MODE="0666", SYMLINK+="rtl_sdr"
Rekomendasi dari http://2h2o.tumblr.com/ install gr-baz dari https://github.com/balint256/gr-baz . Lakukan.


With the vendor and product ids for your particular dongle. This should make the dongle accessible to any user in the adm group. and add a /dev/rtl_sdr symlink when the dongle is attached.
cd /usr/local/src/SDR/
git clone https://github.com/balint256/gr-baz.git


It's probably a good idea to unplug the dongle, restart udev (sudo restart udev) and re-plug in the dongle at this point.
cd /usr/local/src/SDR/gr-baz
chmod +x bootstrap
./boostrap
./configure
make
make check
make install
ldconfig

Latest revision as of 02:45, 16 October 2012

It was recently discovered that several cheap DVB-T usb dongles could be configured to be used as cheap ham radio receivers. Follow along with the discussions here: http://www.reddit.com/r/rtlsdr or find some of the useful software here: http://sdr.osmocom.org/trac/wiki/rtl-sdr

I picked up one of the compatible receivers from ali-express: http://www.aliexpress.com/snapshot/106450763.html

and will document here the steps I took to set it up with gnuradio on ubuntu 12.04.

There are a few things that I won't cover in this instructable, because they deserve an instructable of their own. These include:

1) using the Ubuntu command line (terminal) 2) cloning a git repository 3) building software from source on Ubuntu (especially with cmake)

If anyone has links to stellar, class A++ quality tutorials on any of these things, please add them to the comment and I will link them here.

Setup udev rules

Next, you need to add some udev rules to make the dongle available for the non-root users. First you want to find the vendor id and product id for your dongle.


Create a new file as root named /etc/udev/rules.d/20.rtlsdr.rules that contains the following line: 

SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="2838", GROUP="adm", MODE="0666", SYMLINK+="rtl_sdr"

With the vendor and product ids for your particular dongle. This should make the dongle accessible to any user in the adm group. and add a /dev/rtl_sdr symlink when the dongle is attached.

It's probably a good idea to unplug the dongle, restart udev (sudo restart udev) and re-plug in the dongle at this point.
